@Anoninho Yes! It was SIN T!!! Thank you very much!!
With Damon eq. we know that: ax = d^2x/dt^2 =-L/2 sin T (dT/dt)^2 + L/2 cos T alpha And I suppose that : (dT/dt)^2 is omega^2 and alpha=g*cos T*3/(2*L) that we get from m*g*L/2*cos T=1/3*m*L^2*alpha But putting the numbers (with a correct omega) the answer
